• CVE-2023-0242: 0.56% estimated exploitation activity in the next 30 days; percentile 46.58 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Rapid7 Velociraptor allows users to be created with different privileges on the server. Administrators are generally allowed to run any command on the server including writing arbitrary files. However, lower privilege users are generally forbidden from writing or modifying files on the server. The VQL copy() function applies permission checks for reading files but does not check for permission to write files. This allows a low privilege user (usually, users with the Velociraptor "investigator" role) to overwrite files on the server, including Velociraptor configuration files. To exploit this vulnerability, the attacker must already have a Velociraptor user account at a low privilege level (at least "analyst") and be able to log into the GUI and create a notebook where they can run the VQL query invoking the copy() VQL function. Typically, most users deploy Velociraptor with limited access to a trusted group (most users will be administrators within the GUI). This vulnerability is…

# Patch Next advisory brief: CVE-2023-0242

Advisory: Velociraptor vulnerable to Missing Authorization
IDs: CVE-2023-0242, GHSA-g5vm-525q-r66c
Record: https://patchnext.com/advisories/cve-2023-0242 (revision 1, source checked 26 Oct 2026, 15:09 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: www.velocidex.com/golang/velociraptor 0.6.7-5. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go www.velocidex.com/golang/velociraptor: affected < 0.6.7-5; fixed in 0.6.7-5

## Suggested inspection (read-only)
- Go www.velocidex.com/golang/velociraptor: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on www.velocidex.com/golang/velociraptor.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-g5vm-525q-r66c (GitHub-reviewed advisory GHSA-g5vm-525q-r66c lists affected ranges: Go www.velocidex.com/golang/velociraptor >=0 <0.6.7-5)
